Nige that is contrary to What pirelli say about their tyres. Not doubting your way though glyn

But not contrary to Metzeler or Dunlop. As a matter of interest I was struggling with my wets a bit last year at Pembrey...I couldn't get the bike to turn. Alan Russell of A&R Racing came to me, put more air in my tyres and turned my warmers off. I went back out in the ****ing rain...got my knee down, turned the bike without trouble and delivered my best wet race result ever. On Pirellis.

Believe me...warmers are bad news on wets. If you don't have enough air in the tyres and they are too warm them the tread will fold and squirm, the tyre will deform and you will find it hard to turn the bike because the tyre is not maintaining shape. The difference that I felt was a revelation.

LOL I was told by pirelli Exactly what I posted.. But then again if you read the other thread regarding rosso tyres pirelli are not exactly correct with their statements. Saying that tho I ran my 998 Race bike with the above details at caddy in the wet and had no problems lifting the front whilst still cranked over exiting mansfield, Scared me..... YES it did If it worked for you nige then great, I know a lot of guys run em from cold and let the tyres come to you, Rather than using warmers and having loads of grip on the first 2 corners then binning it on the third because they have gone cold. Horses for courses. Glyn

Yup they are so pointless The Gp and wsb boys use em.......BSB use them and they are on pirelli rubber too, But as I said earlier Horses for courses. This is the info I had from Pirelli, Who as it goes Own Metzeler..

These are a starting point - you may prefer slightly higher or even slightly lower pressure depending on track temperature, riding style, suspension settings etc.

Tyre warmers - if you are going to use them, buy a good quality warmer with thermostatic control. We recommend you use warmers for rain tyres as well as "drys".

Set temperature to 75 degrees C for 1 hour, then set pressures to:

Racetec's - 2.2bar (32psi) front and 2bar (29psi) rear Rain Tyres - 2.3bar (33psi) front and 2.1bar (30psi) rear (I would recommend K1 compound front and rear for Rain tyres) - Only use rain tyres when there is standing water on the circuit. A drying line will destroy the tyres very quickly.

Tyre warmers aren't critical for either tyre, but you will get better performance throughout the life of the tyre if you do use them.
